Abstract
A process for the finish dressing of leathers dressed by a mineral or a combined method, by treatment with an aqueous solution of water soluble polymer dressing substances that are polymers of unsaturated monomers that contain sulfonic groups. These polymers contain, if necessary, additional basic units that do not affect the water solubility, these being derived from the comonomers that can be copolymerized with the monomers that contain the sulfonic groups and which do not contain phosphorus.
